ABSTRACT
Biomedical signals and images have been found to be non-deterministic but describable as chaotic and having fractal properties. These are measured by obtaining the fractal dimension (FD) of the signal or image. The FD of biological signals has been associated with various health and age related factors. This chapter introduces the reader to the brief history of fractal analysis and examines this in terms of biological signals, images and data. The chapter sets the stage for detailed analysis in the subsequent chapters.
